Specifically, the frame 10 is formed with a fitting space 14, the fitting space 14 has an upward opening, and a plurality of counter weights 20 are stack-fitted in the fitting space 14, that is, the respective counter weights 20 enter the fitting space 14 from the opening, so as to be stack-fitted in the fitting space 14. After the respective counterweight blocks 20 are assembled into the assembly space 14, the two upper clamping plates 30 are coupled to the frame 10 with the two upper clamping plates 30 facing and spaced apart, so that the counterweight wheel 40 can be rotatably assembled between the two upper clamping plates 30 with the counterweight wheel 40 positioned at the opening of the assembly space 14. In the first embodiment of the present invention, at least a portion of the counterweight wheel 40 extends into the assembling space 14 in the height direction of the frame 10, that is, the counterweight wheel 40 is at least partially hidden in the assembling space 14 (the counterweight wheel 40 may be partially hidden in the assembling space 14, or completely hidden in the assembling space 14, and when the counterweight wheel 40 is completely hidden in the assembling space 14, an apex of the counterweight wheel 40 facing away from the counterweight block 20 may be a height lower than the opening or equal to the height of the opening), so as to reduce the overall height of the counterweight device.
When the counterweight device is assembled and applied to the running process of the elevator, the counterweight device is wound on the counterweight wheel 40 through the steel rope, the motor of the elevator winds the steel rope, the steel rope drives the counterweight wheel 40 to rotate, and then the counterweight device and the car of the elevator are relatively lifted (namely, when the car ascends, the counterweight device descends, and when the car descends, the counterweight device ascends). In the first embodiment of the present invention, at least a portion of the counterweight wheel 40 assembled between the two upper clamping plates 30 extends into the assembling space 14, that is, the counterweight wheel 40 is partially accommodated in the frame 10, and compared to the conventional counterweight device, the counterweight device adopts the structure that the counterweight frame is mounted on the frame and then the counterweight wheel is arranged on the counterweight frame, so that the counterweight wheel is entirely positioned above the frame, and the counterweight device of the first embodiment of the present invention hides at least a portion of the counterweight wheel 40 into the assembling space 14 of the frame 10, thereby achieving the purpose of reducing the overall height of the counterweight device. Therefore, the height of the top floor or the depth of the pit required by the elevator using the counterweight provided by the embodiment of the utility model is reduced, the design of the elevator is simplified, and the design cost and the installation cost of the elevator are reduced.
As shown in fig. 3 to 5, each upper clamping plate 30 has a first plate section 31, a second plate section 32 and a third plate section 33 which are connected in sequence, the first plate section 31 and the third plate section 33 are respectively located at two sides of the second plate section 32, an end portion of the first plate section 31 far away from the second plate section 32 and an end portion of the third plate section 33 far away from the second plate section 32 extend away from each other, an angle α between the first plate section 31 and the second plate section 32 is set to be greater than or equal to 0 ° and less than or equal to 40 °, an angle β between the second plate section 32 and the third plate section 33 is set to be greater than or equal to 0 ° and less than or equal to 40 °. Each of the upper plates 30 is an integrally formed member, and each of the upper plates 30 may be formed by casting or may be formed by bending a straight plate material. In the first embodiment, each upper clamping plate 30 is preferably formed by bending a straight plate blank.
Correspondingly, the frame 10 includes a first upright 11, a second upright 12 and a cross beam 13, the cross beam 13 is a straight beam, and the first upright 11 and the second upright 12 are respectively fixedly connected to two ends of the cross beam 13, so that a fitting space 14 is formed between the first upright 11, the second upright 12 and the cross beam 13, and the ends of the first upright 11 and the second upright 12 far away from the cross beam 13 form an opening communicated with the fitting space 14. Further, as shown in fig. 2, when the counterweight device is applied to an elevator, a guide block 92 and a slide rail escape preventer 93 are mounted on each of the first and second columns 11 and 12, and a corresponding guide rail (not shown) is provided in an elevator hoistway, on which the guide block 92 and the slide rail escape preventer 93 are slidably fitted. Further, in order to reduce the wear rate between the guide block 92 and the guide rail, oil reservoir members 91 are installed at both the top of the first column 11 and the top of the second column 12, and lubricating oil is supplied between the guide block 92 and the guide rail by the oil reservoir members 91, thereby reducing the wear rate.
When each upper clamping plate 30 is assembled on the frame 10, the first plate section 31 of one upper clamping plate 30 is detachably connected to the first upright post 11 through a bolt and a nut, and the third plate section 33 of the upper clamping plate 30 is detachably connected to the second upright post 12 through a bolt and a nut; the first plate section 31 of the other upper clamping plate 30 is detachably connected to the second upright 12 by means of bolts and nuts, and the third plate section 33 of the upper clamping plate 30 is detachably connected to the first upright 11 by means of bolts and nuts. And, the plate surfaces of the two second plate sections 32 of the two upper clamping plates 30 are parallel to each other, and the counterweight wheel 40 is rotatably assembled on the two second plate sections 32. When the counterweight wheel 40 is assembled between the two second plate sections 32, the symmetrical plane of the counterweight wheel 40 perpendicular to the wheel shaft 41 and the plate surfaces of the two second plate sections 32 are parallel to each other, so that the counterweight wheel 40 is ensured not to generate movement interference with the two second plate sections 32 in the rotating process, and the normal rotation is ensured.

In other embodiments, when the first and second pillars 11 and 12 employ pillars having irregular cross-sectional shapes, then α may not be equal to β.
At this time, a symmetry plane of the assembled weight wheel 40 perpendicular to the wheel shaft 41 is disposed at an angle to the length direction of the weight 20, that is, the weight wheel 40 is rotated at an angle with respect to the weight 20. Like this for the motor of elevator can design the installation more nimble when the top floor is installed, reduces the design of elevator, the degree of difficulty of installation. In fact, for different elevator installation sites, the rotation angle of the counterweight wheel 40 relative to the counterweight block 20 can be selected according to the needs of the installation site, and at this time, the change can be completed only by correspondingly changing the included angle α and the included angle β, so that the included angle α and the included angle β are not limited here.

And, the length of the second clamping plate 72 is less than or equal to the width of the counterweight 20, and the width of the counterweight 20 is greater than or equal to the width of the upright post, so that the whole width of the counterweight device is not widened due to the length of the counterweight pressing plate structure, and the additional occupied space in the elevator shaft is not increased.
